SAN FRANCISCO >> The Giants have already done the hard part, acquiring three-time All-Star Rafael Devers in a shocking, blockbuster trade. They are unquestionably a better team now than they were before the deal.

Now, they’ve got some specifics to work out. Chief among them:

Where will Devers play?

President of baseball operations Buster Posey didn’t have an immediate answer to that question on Sunday following the Giants’ 5-4 loss to the Los Angeles Dodgers. Before making a decision, the Giants’ brass will meet with Devers in person to discuss his best fit.

“I think that’s a conversation that we’re going to have to have with him,” Posey told beat writers Sunday night. “I want to do my best to be upfront and transparent with these guys and make sure we’re on the same page. That’s a conversation for myself, Zack (Minasian), and Bob to have with him.”

Devers, who has a career .859 OPS, arrives in San Francisco following something of a falling out with the Red Sox.

When Boston signed Alex Bregman — another third baseman — to a three-year, $120 million contract in February, Devers said he wouldn’t move off third base. Devers later relented and transitioned to the designated hitter role.Three months later, Red Sox first baseman Triston Casas suffered a season-ending injury. Despite the opening, Devers declined the team’s request for him to play first base — a position he has never played in the majors or minors.

On Sunday, Posey shared that Red Sox chief baseball officer Craig Breslow told him “some of the stuff that was in the media was a bit unfortunate.” Posey added he had heard from others that Devers is a “great teammate” who “loves to play the game.” Willy Adames and Dominic Smith praised Devers’ character as well.

“He’s a great guy,” Adames said. “Obviously, there has been some miscommunication there. From what I know about him ... he wants people to communicate with him and be honest. I feel like here with Buster, that’s all we’ve got. Buster is a super honest guy. He’s going to be straight up and (Devers) is going to love that. He’s going to feel comfortable here.”

For the time being, the Giants may not have to worry about finding Devers a position.

Matt Chapman, a five-time Gold Glover, is currently on the 10-day injured list due to inflammation in his right hand and won’t begin rehab until later this week. Casey Schmitt has done well as Chapman’s replacement, but he fouled a ball off his left ankle on Sunday and was diagnosed with a [cq comment=”left ankle “ ]contusion. If Chapman and Schmitt are both out, Devers stands to slide right in.

Devers was exclusively used as a designated hitter this season in Boston but has played 951 games at third in the majors. He rates out as a below-average defender, worth -62 defensive runs saved and -28 outs above average in his career, but he knows the position.

Alternatively, the Giants could be proactive about Devers’ future before Chapman returns. If Schmitt doesn’t need to go to the injured list, the Giants could keep Schmitt — the better defender — at third, put Devers in the DH role, and have Wilmer Flores split time with Dominic Smith at first base.

The Giants have kept Flores, who leads the team with 51 RBIs, mostly at DH to keep him healthy after he underwent a season-ending Tenex procedure last year on his right knee. After signing Smith earlier this month, San Francisco could ensure Flores’ workload doesn’t get too high. But given Flores’ importance to this offense — Flores’ 1.012 OPS with runners in scoring position leads the team — would the Giants want to limit his opportunities?

There’s also the option that Devers refused in Boston: play first base. Perhaps Devers, playing on a new team where he no longer has seniority, would be more willing to transition to a new position.
